• JAWS Motorsport's E60 M5 hits 518 horsepower to the wheels and 8600 RPM on the S85 V10 with their Alpha-N tune

      Impressive naturally aspirated and stock internal work here on the S85 V10 by BimmerBoost vendor JAWS Motorsport. The car put down a baseline of 448 wheel horsepower on a DynoMite dyno with just intake scoops. From that baseline JAWS was able to hit 518 wheel horsepower with addition of their one piece plenum, Alpha-N tune with 8600 RPM limiter, and secondary cat delete. That is a gain of 70 horsepower at the wheels.

      Keep in mind that this was done on pump fuel with the stock exhaust (other than secondary cat delete) and stock headers. Is there more to be gained here? Absolutely and we expect an update as JAWS revises their tune with their headers that are being finished up. We have no idea how much more they will hit but the results so far are definitely impressive and this is one of the strongest naturally aspirated S85's we have seen. Pictures, graphs, and video below.

        Ok Thanks but too over priced for me. Good work though.
        The airbox is one piece and a complete replacement so not cheap.

        Their tune and upcoming headers though are priced pretty darn well.

        Dynojet around 420 with charcoals in place. The baseline here was around 450 but with scoops.

        Yes, headers plus full exhaust. So they will pick up more.

        They should have been done long time ago, now they are almost ready but i cannot say a date..we must put them on our car and dyno it first, so the power output from headers only will only be a guess at first point :/
